See the list and localisation of the Portuguese Network of Mobility Centres.
There you can get local and personalised assistance. The Portuguese Mobility
Centres are members of the European Network of Mobility Centres ERA-MORE.

The mission of ERA-MORE is to provide comprehensive and up-to-date information
and personalised assistance to all researchers and their families seeking
advice in issues relating to their move across borders. ERA-MORE Mobility
Centres provide information and assistance in matters such as entry conditions,
visas, work permits, recognition of diplomas, job opportunities, salaries,
taxation, pension rights, health care, social security, accommodation, day
care, schooling, language courses, access to culture of the host country and
IPR. Mobility Centres fulfil this task either directly, by providing direct
information and proximity assistance to the person(s) requesting help, or
indirectly, by directing the person(s) concerned the closest specialised
centre. There are currently about 200 Mobility Centres in 32 countries. In the
second half of 2006 about 16.000 researchers got help from ERA-MORE.
